The strains were lysed only by The relative severity of the GI illness manifested by a large number of patients in the food poisoning OB, the increased number of serotype 4,5,12:i:− strains confirmed among HP in NYC, and the unique serologic and biochemical profiles of these A case of illness in this OB was strictly defined as at least three episodes of diarrhea per day, abdominal pain, and fever.
The genus Salmonellais divided into two species, entericaand bongori. A serotype (as well as a serovar) is determined by the somatic (O) and flagellar (H) factor antigens present in the cell wall of From January 1998 through December 2000, the Public Health Laboratories (PHL) confirmed 82 referral strains of a newly emerging serotype, 4,5,12:i:−, without the second-phase H antigen (monophasic).
A 2014 study showed that Most infections are due to ingestion of food contaminated by animal feces, or by human feces, such as by a food-service worker at a commercial eatery. Biochemically, however, the serotype 4,5,12:i:− strains differed slightly but consistently from serotype Typhimurium strains as well as from other The serotype 4,5,12:i:− strains also showed an antibiogram profile (Table On PFGE analysis, the serotype 4,5,12:i:− strains showed less heterogeneity (i.e., 18 PFPs and 67 strains) than the serotype Typhimurium strains (6 PFPs and 8 strains). They are facultative anaerobic chemoorganotrophs. Salmonellae belong to the family Enterobacteriaceae and are a medically important pathogen for both humans and animals. Nineteen of 34 persons (56%) who submitted stool specimens tested positive for serotype 4,5,12:i:−.
Both groups must enter by crossing the barrier created by the intestinal cell wall, but once they have passed this barrier, they use different strategies to cause infection. They were isolated from patients in 17 New York City (NYC) hospitals (HP), private laboratories (PL), and a single food poisoning outbreak (OB) involving 110 healthy adults attending a dinner reception in Queens, New York. Salmonella enterica subsp. Find articles by S. Porwollik. S. enterica has six subspecies, and each subspecies has associated serovars that differ by antigenic specificity. It can give some idea about risk. A variety of vegetables and sprouts may also have salmonella.
For the disease caused by such bacteria, see F. Kauffmann: Die Bakteriologie der Salmonella-Gruppe. An infection can only begin after living salmonellae (not merely While in developed countries, nontyphoidal serotypes present mostly as gastrointestinal disease, in sub-Saharan Africa, these serotypes can create a major problem in bloodstream infections, and are the most commonly isolated bacteria from the blood of those presenting with fever. Salmonella is classified into >2500 serovars based on the Kauffmann–White scheme (Popoff et al., 2003).

The species Salmonella entericais further subdivided into six subspecies that are designated by taxonomic names; these are sometimes abbreviated by Roman numerals. The size of the rods ranges from 0.7–1.5 μm to 2.2–5.0 μm; Salmonella produces colonies of approximately 2–4 mm in diameter.
Two species are currently recognized in the genusSalmonella,S.

By Dice coefficient analysis (It is tempting to speculate that serotype 4,5,12:i:− is related to but distinct from serotype Typhimurium or serotype Lagos; however, the above tests are not conclusive.
Among the >2500 Salmonella serovars, several serovars have been identified as major pathogens to humans and domestic animals, including Salmonella Typhimurium, Enteritidis, Typhi, Newport, Heidelberg and Paratyphi A. Salmonellae are divided taxonomically into two species: Salmonella enterica and Salmonella bongori (subspecies V). The gastrointestinal illness (GI) manifested in this OB by 86 people was severe enough to require hospitalization of 31 of 44 persons (70%) who sought emergency consultation. Salmonellais now considered to consist of two species, Salmonella bongoriand Salmonella enterica, and S. entericais further classified into six subspecies, arizonae(IIIa), diarizonae(IIIb), houtenae(IV), salamae(II), indica(VI), and enterica(I) (7). Most of the human pathogenicSalmonella serovars belong to the enterica subspecies.
